PREFACE

Central Water Commission had started Flood Forecasting & Warning service in India in November 1958 by setting one forecasting station at Old Delhi Bridge, for the national capital, on the river Yamuna. Today, its network of Flood Forecasting and Warning Stations gradually extended covering almost all the major inter-state flood prone river basins throughout the country. It comprises of 175 Flood Forecasting Stations including 28 inflow forecast in 9 major river basins and 71 sub basins of the country. It covers 15 states besides NCT Delhi and UT of Dadra & Nagar Haveli. The flood forecasting activities of the Commission are being performed every year from May to October through its 20 field divisions which issue flood forecasts and warnings to the civil authorities of the states as well as to other organizations of the central & state governments, as and when the river water level touches or is expected to cross the warning level at the flood forecasting stations. Inflow Forecasts are issued for 28 reservoir/dam/barrages. The forecasts are formulated whenever the inflow into the dam exceeds the threshold value fixed by the respective project authorities for reservoir regulation as well as flood moderation.

The flood season 2013 witnessed unprecedented flood events at 3 stations in the rivers Alaknanda, Ganga and Yamuna in the country. High Flood Situation was witnessed at 21 stations in River Brahmaputra in Assam; River Yamuna at Delhi Railway Bridge; River Alaknanda and Ganga in Uttarakhand; Rivers Subarnarekha, Burhabalang in Odisha; River Ganga, Ghaghra and Rapti in Uttar Pradesh, River Wardha in Maharashtra and River Ganga, Ghaghra and Kosi in Bihar. The year witnessed moderate to low intensity floods in many other parts of India. The highlight was the floods in October in association with Cyclonic Storm “Phailin” when flood/inflow forecast stations in Odisha got heavy flows in association with very heavy to exceptionally heavy rainfall.

During the year 2013, a total of 7060 forecasts were issued out of which 6760 forecasts (95.75%) were found to be within the limits of accuracy. The number of level forecasts issued during the year 2013 were 5741 out of which 5471 (95.30%) was within the limit of accuracy of ±0.15 m. The number of inflow forecasts issued was 1319 out of which 1289 (97.73%) were within limits of accuracy of + 20%.

The Telemetry data have been received in all Divisions. Chambal Division (Jaipur), ERD (Bhubaneshwar), Mahanadi Division (Burla), LKD (Hyderabad) etc. are

i successfully using Telemetry data for flood forecasting through Mathematical Model. Other Divisions are also making attempt to use the Telemetry data by developing MIKE 11 model for Flood Forecasting in their jurisdictions.

The level of performance achieved, has been possible as a result of the dedicated team work of the officers and staff manning the various activities of hydrometeorological observations & flood forecasting and monitoring the flood forecasting activities of the field offices.

India Meteorological Department (IMD) through its Flood Meteorological Offices (FMO) also helped in this endeavour by providing all the Meteorological inputs for formulation of Flood Forecasts. CWC wishes to place its acknowledgements for the services provided by IMD through its various FMOs.

Flood Forecast Monitoring (FFM) Directorate plays an important role in compiling the information received from various field offices at Headquarters and issues daily bulletins which are sent to various offices of the MOWR, MHA, Railway Board, Transport Ministry and Ministry of Agriculture. I wish to place on record my deep appreciations of the efforts put in by the officers and staff of FFM Directorate in carrying out the work with utmost devotion & dedication in bringing out this report. The staff of this Directorate, along with other supporting staff from other Directorates attached to this Directorate during flood duties in the flood season of 2012 also deserves all appreciation in keeping the control room fully functional on all the week days, including holidays, Saturdays & Sundays. The control room was kept operational round the clock throughout the flood season.

It is hoped that the momentum gained in improving performance, innovations in evaluation, modernization as well as computerization, year after year, will be further accelerated to achieve greater accuracy of each and every forecast especially in high and unprecedented flood situations with the help of mathematical modelling supported by real-time data from telemetry.

Suggestions/comments of the Users of this report with a view to further enhance its usefulness are welcomed and will be incorporated in the next edition.

EXECUTIVE SUMMARY

0.1 Meteorological Situation

During 2013, the rainfall for the country as a whole, for the season (June-September) was 106 % of its long period average (LPA). Seasonal rainfall was 109% of its LPA over Northwest India, 123% of its LPA over Central India, 115% of its LPA over south Peninsula and 72% of its LPA over Northeast (NE) India. Out of the total 36 meteorological subdivisions, 14 subdivisions constituting 48% of the total area of the country received excess season rainfall, 16 subdivisions (38% of the total area of the country) received normal season rainfall and the remaining 6 subdivisions (14% of the total area of the country) received deficient season rainfall. Monthly rainfall over the country as a whole was 132% of LPA in June, 106% of LPA in July, 98% of LPA in August and 86% of LPA in September. Southwest monsoon current advanced over the Andaman Sea 3 days earlier than its normal data of 20th May and set in over Kerala on its normal date of 1st June. The southwest monsoon covered the entire country by 16th June, about 1 month earlier than its normal date of 15th July. The withdrawal of monsoon from west Rajasthan commenced on 9th September compared to its normal date of 1st September. After 19th, further withdrawal of southwest monsoon was stalled with the successive formation of two low pressure areas and their westward movement across the central parts of the country. During the season, 2 monsoon depressions and 16 monsoon low pressure areas were formed as against the normal of 6 monsoon depressions and 6 monsoon low pressure areas per season. During October, Very Severe Cyclonic Storm “Phailin” formed over Bay of Bengal on 9th October 2013 and crossed Odisha coast on 12th October 2013.

0.2 Flood Situation

During the year 2013, three of the level forecasting sites namely, Srinagar on river Alaknanda, Mawi on river Yamuna and Bhagalpur on river Ganga crossed the Highest Flood Level and experienced Unprecedented Flood.

High Flood Situation was witnessed at 21 sites viz., River Alaknanda at Srinagar, River Ganga at Rishikesh, Haridwar, Ghazipur, Ballia, Patna (Gandhighat), Hathidah, Bhagalpur and Kahalgaon, River Yamuna at Mawi and Delhi Railway Bridge, River Ghaghra at Elgin Bridge and Gangpur Siswan, River Rapti at Balrampur, River Kosi at Basua, River Brahmaputra at Dibrugarh and Neamatighat, River Desang at Nanglamoraghat, River Wardha at Balharsha, River Subarnarekha at Rajghat and River Burhabalang at N H 5 Road Bridge.

Moderate to Low floods were witnessed in most of basins at various Flood Forecasting Stations. No forecasts were issued for 35 stations as they did not cross warning level or warning criteria.

The highlights of this year‟s flood included the severe flooding in Uttarakhand in June 2013 in association with early onset of South West Monsoon, continuous Moderate Flood in Lower Yamuna and Chambal Basins which gave rise to flooding in main Ganga after the confluence with Yamuna. The low flood in Upper Yamuna during February 2013 was also a highlight of this year and CWC issued forecast for this flood.

0.3 Flood Forecasting Performance

During the year 2013, 7060 forecasts were issued out of which 6760 forecasts (95.75%) were found to be within the limits of accuracy. The number of level forecasts issued during the year 2013 were 5741 out of which 5471 (95.3%) was within the limit of accuracy of ± 0.15 m. The number of inflow forecasts issued was 1319 out of which 1289 (97.73%) were within limits of accuracy of ±20%.

CHAPTER-1

NATIONAL FLOOD FORECASTING NETWORK

1.1 FLOOD FORECASTING SERVICES

Flood causes considerable damage to human lives and property almost every year. About one third of total flood prone area (40 mha assessed by the Rashtriya Barh Ayog) of the country has been provided with reasonable protection against flood of a low magnitude due to technological and economical constraints but there is no protection from floods of higher magnitude. Since adoption of National Flood Policy by Government of India in 1954, it was realized that a total protection against flood by structural means alone is not possible and that optimum solution would consist of a mixture of structural and non-structural measures. Therefore, stress has been laid on non-structural measures like flood forecasting and warning, which is most important among such means to minimize the damage potential from floods. Accurate and timely flood forecasts and advance warning have, therefore, to be aimed for providing valuable time to the people and to civil authorities in taking preventive measures like evacuation, relief and rehabilitation measures, preparedness for flood fighting by engineering authorities etc. and thus mitigating such loses from floods.

1.2 FLOOD FORECASTING NETWORK IN THE COUNTRY

Flood Forecasting has been recognized as the most important, reliable and cost effective non-structural measures for flood mitigation. Recognizing the great importance of this measure, flood forecasting of river Yamuna at Delhi was suggested by Reddy Committee set up by Prime Minister, Govt. of India to manage flooding of Delhi. Accordingly in the year 1958, CWC commenced the flood forecasting service in a small way by establishing flood forecasting unit for issuing water level forecasts of the Yamuna for the National Capital, Delhi. On the recommendation of various committees/panels, a "Flood Forecast & Warning Organisation" was set up in CWC in 1969 to establish forecasting sites on inter-state rivers at various flood prone places in the country. 41 forecasting sites were added in 1969, making total number of forecasting sites to 43. Extension of the service followed from time to time and now the river forecasting has been expanded over the years to cover nine major inter-state flood prone river basins, which comprises of 71 sub-river basins traversing the country. The year-wise positions of the number of flood forecasting sites till the flood season 2013 in the network of Central Water Commission are shown in the Table 1.1:

Table-1.1: Yearwise positions of number of forecasting sites in CWC

The “National Flood Forecasting and Warning Network” of Central Water Commission, which comprised of 175 flood forecasting sites including 28 inflow forecasting sites in flood season 2013 is shown in Map-1. The number of flood forecasting sites on each of the nine major inter-state river systems, which constitutes 71 river sub-basins in the country, are given in the Table 1.2.

Central Water Commission through its twenty flood forecasting divisions issued forecasts to the various user agencies, which includes various civil / engineering agencies of the States/ Central Governments such as Irrigation/ Revenue/ Railways/ public undertakings and Dam/ Barrage Authorities/ District Magistrates/ Sub Divisional Officers besides the Defence Authorities involved in the flood loss mitigation work. During the flood season, the Hon‟ble Minister of Water Resources, Government of India, the Chairman and the Member (River Management) of Central Water commission were also being apprised of the latest flood situations in the above river basins in the country.

1.3 CLASSIFICATIONS OF VARIOUS FLOOD SITUATIONS

The Central Water Commission has categorized various flood situations, for monitoring the floods in the country though its flood forecasting network, into the following four different categories, depending upon the severity of floods i.e. based on floods magnitudes.

1.3a Level Forecast

(i) LOW FLOOD

The river is said to be in “LOW FLOOD” situation at any flood forecasting sites when the water level of the river touches or crosses the warning level, but remains below the danger level of the forecasting site.

(ii) MODERATE FLOOD

If the water level of the river touches or crosses its danger level, but remains 0.50 m below the Highest Flood Level of the site (commonly known as “HFL”) then the flood situation is called the “MODERATE FLOOD” situation.

(iii) HIGH FLOOD

If the water level of the river at the forecasting site is below the Highest Flood Level of the forecasting site but still within 0.50m of the HFL then the flood situation is called “HIGH FLOOD” situation. In “High Flood Situations” a special “Orange Bulletin” is being issued by the Central Water Commission to the users agencies which contains the “special flood message” related to the high flood.

(iv) UNPRECEDENTED FLOOD

The flood situation is said to be “UNPRECEDENTED” when the water level of the river crosses the “HIGHEST FLOOD LEVEL” recorded at any forecasting site so far. In “Unprecedented Flood Situations” a special “Red Bulletin” is being issued by the Central Water Commission to the users agencies which contains the “special flood message” related to the unprecedented flood.

1.4 Standard Operating Procedure (SOP) for Flood Forecasting & Warning

The basic activity of data collection, its transmission and dissemination of flood forecasts to the local administration is carried out by the field divisions of CWC. The modelling centres and Divisional Flood Control Rooms (DFCR) are located in the premises of the field divisions. The field divisions perform these activities as per existing Manual on Flood Forecasting which contains the following critical activities as the general SOPs

1. Nomination of Nodal Officers of CWC for interaction with the Nodal Officers of concerned State Governments before monsoon every year. 2. Gearing up of flood forecasting network before monsoon every year. 3. Operation of Divisional Flood Control Room during monsoon every year 4. Operation of Central Flood Control Room (CFCR) during monsoon every year.

5. Issue of flood forecasts to designated officers of concerned State and transmission thereof through FAX/Telephone/E-mail/ through Special Messengers during monsoon every year. 6. Sending flood alerts through SMS on Mobile Phones to the concerned officers of State/ Central Government during high and unprecedented flood situations as per Standard Operating procedure (SOP) for issuing alerts and electronic messaging in the event of disaster situations issued by National Disaster Management Division, Ministry of Home Affairs, vide letter No: 31-32/2003-NDM-III / II dated 10th April 2006, made effective from 24th April 2006.

For the purpose of dissemination of alerts to PMO/ Cabinet Secretariat, a uniform system has been devised by categorizing each type of alert in stages- Yellow, Orange and Red.

Categories of alerts for flood in respect of level forecasts is as indicated below.

Category Description Stage IV Low Flood (Water level between Warning level and Yellow Danger level) III Moderate Flood (Water level below 0.50m less than Yellow HFL and above Danger Level) II High Flood (Water Level less than Highest Flood Orange Level but still within 0.50 m of the HFL) I Unprecedented Flood (Water Level equal and above Red Highest Flood Level-HFL)

1.5 Inflow Forecasts

Inflow Forecasts are issued for 28 dams/reservoirs/barrages in various river basins in the country. The project authorities have identified the threshold inflow limits for issue of forecast considering various factors such as safety of the dam, status of reservoir, downstream channel/ canal requirements. As discussed in the previous section, the criteria for issue of High and Unprecedented floods are applicable only to level forecast. However, they are not applicable for inflow forecasts. In view of the unprecedented floods in Krishna, it is high time that similar criteria are fixed for inflow forecasts too. Locally some of the reservoirs in Krishna and Godavari Basins have categorized certain inflow figures for warning downstream areas for Low, Moderate, High and Unprecedented situations, it has still not been recommended for all the reservoirs in the country as a whole. The categorization of inflow shall be done taking into account the total live storage of the reservoir and the largest design flood discharging capacity and the likely effect of this discharge on the downstream areas, for each inflow forecast stations. The inflow in volume during the given duration indirectly indicates the possibility of accommodating the given volume or otherwise in

8 the reservoir. The outflow pattern is decided keeping in view of the safety measures at the reservoir and the likely impact of the outflow from the reservoir to cause damages/ difficulties in the downstream areas giving due attention to the Emergency Action Plan (EAP) of the project. Thus, the criteria should cover all the aspects of the flood pattern at the reservoir as well as the downstream.

1.6 EXPANSION OF THE NETWORK OF FLOOD FORECASTING SITES

The operation and maintenance of existing flood forecasting network is carried out as per budget allotment each year under „Non-Plan‟ head and is thus subject to such restrictions and cuts applied to items under `Non-Plan'. The allocation during the year 2013-14 was Rs. 2.94 Crore only including that for payment to Government of Bhutan for maintaining hydrometeorological stations in river common to India and Bhutan and strengthening & Modernization of FF and Hyd. Obs. Network in Brahmaputra and Barak Basin. The expansion of the network with a view to cover additional flood prone areas is proposed to be covered under „Plan‟ head. Work on such Plan schemes is subject to approval of specific schemes by the Government and the budget allocation of funds.

The salient features of all Flood Forecasting Sites, The details of all the sites basin-wise as well as Statewise during the flood season 2013, is shown at Annex-I, Annex-II and Annex-III respectively.

1.7 Data Communication System

Central Water Commission maintains 544 Wireless Stations for near real –time data communication. In addition, satellite based Telemetry System has been installed/ or under installation at 445 stations for automatic data communication. As the wireless works on pre-fixed schedules and the Telemetry transmit the data at pre-fixed time intervals only, telephone/mobile phone, fax and internet in particular was used for receiving the vital hydrometeorological data immediately after its observation and dissemination of flood forecasts to user agencies.

1.7.a Wireless Communication

Wireless network in CWC consists of HF (3 to 30 MHz) and VHF (30 to 300MHz) sets. The HF sets are used for long distance communication between Site and Division (15 to 20Watts), Division to Division (20 to 100 Watts) and Division to CWC Headquarters (100 to 500 Watts). VHF sets are used for short distance communication (i.e. from river to Site office).

Wireless network works on pre-fixed schedules only. The schedules are decided by the respective field divisions and intimated well in advance to all the stations under their jurisdiction for strict compliance. The wireless

9 schedules from divisions to CFCR are generally operated between 0700-0800 for collecting 06 hrs data, 0900- 1000 for collecting 08 hrs data, 1000-1100 for collecting forecast, 1530-1630 for collecting 1500 hrs data and 1830-1930 hours for collecting 18 hrs on normal days and throughout night in case of High or Unprecedented Flood Situations.

1.7b Telemetry

Sensor based data collection and satellite based communication was installed at 223 sites upto X plan for real time hourly water levels, hourly rainfall and other important meteorological parameters, established in Krishna, Godavari, Mahanadi, Chambal Damodar Yamuna and Brahmaputra Basins.. Two earth stations (DDRGS) located at Jaipur and Burla are receiving through INSAT/Kalpana satellite, the data from remote stations for further transmission to the respective modelling centre through VSAT. The data received was used mainly by the divisions issuing forecast by MIKE-11. Data from 52 sites was not received because of theft, vandalism and damage due to floods. Installation of sensor based Telemetry System at 222 sites was in progress.

1.8 DAMAGE DUE TO FLOODS/ HEAVY RAINS BETWEEN 1953 TO 2013

The damage due to floods for the entire country was estimated to be Rs.10092.70 Crore during the flood season 2013. The average annual damages to crops, houses and public utilities from the year 1953 to 2013 as reported by the States/UT‟s are of the order of Rs. 3800.175 Crore, the maximum annual damage being Rs.32551.758 Crore during 2009. A comparative details showing the details of damages occurred during the flood season 2010 to 2013 on different accounts, based on the reports (tentative), received from the revenue authorities of the state governments is given in the Table 1.4.

CHAPTER – 2

ROLE OF IMD IN FF ACTIVITIES AND SOUTHWEST MONSOON ACTIVITIES

2.1 Role of IMD & SOUTHWEST MONSOON

2.1a Role of IMD

India Meteorological Department (IMD) provides various Meteorological inputs for formulation of Flood Forecast in Divisional Flood Control Rooms (DFCR) of CWC. The inputs include rainfall in stations other than those operated by CWC on different sub-catchments of river basins, providing Quantitative Precipitation Forecast (QPF) for 24 hours, Weather Situation and Heavy Rainfall Warnings over various basins and outlook for further 48 hours. The QPFs are issued by 0930 hours daily and are modified if necessary around 1230 hours. For this purpose, IMD is operating Flood Meteorological Offices (FMO) in different river basins. These are located at Agra, Ahmedabad, Asansol, Bhubaneshwar, Delhi, Guwahati, Hyderabad, Jalpaiguri, Lucknow and Patna. These FMOs provide all the weather related inputs to the concerned DFCR by fastest available modes of communication. The FMOs are also provided the rainfall figures observed by the stations operated by CWC as well as the water level in the flood forecast stations in the basin by the concerned DFCR.

During the year 2013, the Hydrology division of IMD provided online QPF by using two Numerical Weather Prediction (NWP) models namely WRF ARW (9km x 9km) and Multi Model Ensemble (MME) for various sub- basins of different river basins.

The FMO at Hyderabad uploaded the daily weather summaries, QPF and rainfall figures issued in the web site of Meteorological Centre Hyderabad during the flood season from 15th June to 15th October. However, the bulletins during non-monsoon period in first week of November in association with Depression were not uploaded in the Website by FMO, Hyderabad. Other FMOs have not uploaded their bulletins in the concerned websites of Regional or Meteorological Centres. During the expansion of flood forecasting network under the XII Plan, it was also agreed that the concerned Regional/ Meteorological Centre falling within a basin will issue the QPF and provide Meteorological inputs for the additional basins where expansion is contemplated.

The INSAT-DRT secretariat of IMD looks after the works of allocation of Station Index number, Time slot allotment and frequency allocation for the various Automatic Weather Stations setup by different organisations. CWC is one of the members of INSAT-DRT User and officers of CWC attend the INSAT-DRT User meetings convened by the INSAT DRT Secretariat of IMD.

CWC has so far installed 445 Satellite based Automatic Data Collection Units for collection of Hourly Water Level and Rainfalls from remote stations. IMD has allocated the Station Index Numbers and other parameters for all these stations. During the first year of the 12th Plan there is a proposal to install 125 automatic data collection units in various river basins and IMD has provided the Station Index numbers/ Time slot/ Frequency for these 125 stations. Another 81 stations have been identified for upgradation during the year 2013-14 for which, IMD has been approached for providing Station IDs etc.

2.1b Southwest Monsoon

India gets about 80% of its Annual rainfall during the south-west monsoon from June to September except some portions of south-eastern parts of peninsular India where the main rains occur during the period of north-east monsoon from October to December, which overlap with the receding stage of the south-west monsoon in October. Occasionally, cyclonic storm develop in the south-west bay and move into the Peninsula and produces heavy rain during north-east monsoon season.

Southwest monsoon advances from Kerala in the beginning of June. It produces spell of heavy rainfall along the western coast of the peninsula and on the southern slopes of Khasi and Jaintia hills in north- eastern region.

In association with the depression which occasionally form in the North Bay of Bengal and move north-westwards, heavy rains are produced in the central parts of the country, Orissa, Gangetic West Bengal, southern districts of Bihar, Gujarat region, and East Rajasthan and in the later monsoon months in and around North Deccan.

A very important characteristic of southwest monsoon is the occurrence of "break". The break situations arise when the monsoon trough shifts to the Himalayas and are very important as these cause floods in the rivers rising from the Eastern Himalayas. Sometimes, the phenomenon of break sets in immediately after a monsoon depression has occurred. These two causes occurring in succession serve to intensify the floods.

The whole India has been divided into 36 meteorological sub-divisions by India Meteorological Department (IMD) for the purpose of studies of rainfall/monsoon activities.

The progress of monsoon rainfall over the country is monitored by evaluating the departures of total rainfall from the normal rainfall in respect of meteorological sub-divisions and districts. The IMD has classified the rainfall as excess, normal, deficient and scanty, according to the following criteria.

Excess : + 20% or more than normal Normal : + 19% to - 19% of the normal Deficient : - 20% to - 59% of the normal

Scanty : - 60% to - 99% of the normal No Rain (N.R.) : - 100% of the normal

Normal is defined as the Long Period Average say for 50 years for the period from 1st June to 30th September. Presently Long Period average for the years 1951 to 2000 is being used to define normal. For the country as a whole the normal rainfall during the period 1st June to 30th September is 89 cm.

2.2 HIGHLIGHTS OF SOUTH-WEST MONSOON 2013

 For the country as a whole, the rainfall for the season (June- September) was 106 % of its long period average (LPA).

 Seasonal rainfall was 109% of its LPA over Northwest India, 123% of its LPA over Central India, 115% of its LPA over south Peninsula and 72% of its LPA over Northeast (NE) India.

 Out of the total 36 meteorological subdivisions, 14 subdivisions constituting 48% of the total area of the country received excess season rainfall, 16 subdivisions (38% of the total area of the country) received normal season rainfall and the remaining 6 subdivisions (14% of the total area of the country) received deficient season rainfall.

 Monthly rainfall over the country as a whole was 132% of LPA in June, 106% of LPA in July, 98% of LPA in August and 86% of LPA in September.

 Out of the total of 641 districts, 100 were affected by moderate meteorological drought (seasonal rainfall deficiency of 26% to 50%), while 39 were affected by severe meteorological drought (seasonal rainfall deficiency of 51% to 99%)

 Southwest monsoon current advanced over the Andaman Sea 3 days earlier than its normal data of 20th May and set in over Kerala on its normal date of 1st June. The southwest monsoon covered the entire country by 16th June, about 1 month earlier than its normal date of 15th July.

 The withdrawal of monsoon from west Rajasthan commenced on 9th September compared to its normal date of 1st September. After 19th, further withdrawal of southwest monsoon was stalled with the successive formation of two low pressure areas and their westward movement across the central parts of the country.

 The sub-divisionwise South West Monsoon rainfall during June to September 2013 is shown in the Following Map-2.

Map-2 Sub-divisionwise South West Monsoon rainfall during 2013

2.3 ONSET OF SOUTH-WEST MONSOON SEASON 2013

Associated with the formation of Cyclonic Storm Mahasen (10th - 16th May) over southeast Bay of Bengal, low level cross equatorial monsoon flow strengthened over south Andaman Sea and adjoining south Bay of Bengal. This subsequently resulted in the advance of southwest monsoon over Andaman Sea and some parts of southeast Bay of Bengal on 17th May, 3 days before the normal date of 20th May. Cross equatorial flow over the Arabian Sea remained strong since the advance of southwest monsoon over the Andaman Sea.

The southwest monsoon set in over Kerala on 1st June, on its normal date. The same day, monsoon advanced over entire south Arabian Sea, Maldives- Comorin area, Lakshadweep, some parts of central Arabian Sea, entire Kerala, some parts of Coastal & South Interior Karnataka and most parts of Tamil Nadu. Convectively active phase of the Madden - Julian Oscillation (MJO) and the associated systematic northward propagation of the east-west shear zone at the mid-tropospheric levels during the subsequent period helped faster advance of monsoon and increased rainfall activity over the country.

The pace of advance of southwest monsoon this year had been the fastest during the period 1941-2013. Since the onset took place over Kerala on 1st June, it rapidly covered the south peninsula and northeast India by 9th June and central, eastern parts and western Himalayan region by 15th June. This was also aided by the formation and west- northwestward movement of a low pressure area along the east-west trough during the same period. On 16th June, presence of this low pressure area over east Rajasthan & neighbourhood superposed with a trough in the mid & upper tropospheric westerlies provided conditions conducive for the large scale convection and wide spread monsoon rains over northwest India. This helped monsoon to advance of monsoon over the entire country on 16th June, about a month earlier than its normal date of 15th July.

Fig.2.1 shows the isochrones of advance of monsoon 2013.

Fig. 2.1 Advance of southwest Monsoon–2013.

2.4 CHIEF SYNOPTIC FEATURES

Strong cross equatorial flow prevailed during June and July. It gradually weakened during the latter half of the season. The axis of monsoon trough remained in its near normal position and extended upto lower tropospheric levels without its characteristic southward tilt with height during most parts of the season. The seasonal „heat low‟ weakened from the beginning of September. Subsequently, the axis of monsoon trough also weakened and thereby became less delineated at mean sea level since 4th September.

Though no typical break situation developed during the season, the rainfall pattern from the end of August to the first week of September resembled break like, as a consequence to the overall weakening of the monsoon circulation.

During the season, only 2 monsoon depressions were formed against a normal of 6 depressions per season. However, 16 monsoon low pressure areas were formed against a normal of 6 low pressure areas per season. The tracks of the 2 monsoon depressions are given in Fig.2.2 One depression formed over the Bay of Bengal in the month of July and another formed over land in August. During the last about 30 years, there were two years (1984 and 1996) when 18 low pressure areas had formed in the monsoon season. During each of both these years, 3 low pressure areas had intensified into depressions. Out of the sixteen low pressure areas formed during this season, 12 formed over the Bay of Bengal, 3 formed over land and one formed over the Arabian Sea. The month wise break up is 3 in June, 4 in July, 5 in August and 4 in September. The first low pressure area (4th-5thJune) formed over the Arabian Sea under the influence of cyclonic circulation embedded in the shear zone during the onset phase. Though it was short lived, the formation of this low pressure area stalled the advance of the Monsoon over the Arabian Sea for 3 days (5th - 7th June). However, the second low pressure area which formed over the Bay of Bengal moved west-northwestwards during 12th – 17th June upto Rajasthan and Haryana and its interaction with a trough in the mid & upper tropospheric westerlies helped the monsoon to cover the entire country. During July one low pressure area (10th-13th July) formed over land and 3 low pressure areas (15th – 17th July, 19th-25th July, 25th-29th July) formed over the Bay of Bengal. All these 4 low pressure areas and one depression (30th-31st July) that formed over the Bay of Bengal moved northwestward along the monsoon trough and helped to maintain the monsoon activity over the region.

The cyclogenesis during the second half of the season had a major contribution from the remnant vortices from the east. A land depression formed during 20th-22nd August over Gangetic West Bengal and adjoining northwest Bay of Bengal dissipated over east Madhya Pradesh. The five low pressure areas that formed in the month of August were mostly of short duration. Two dissipated in-situ and were of 1 day duration, two moved up to east Uttar Pradesh and adjoining areas and the low pressure area during 9th-

11th August dissipated over west Uttar Pradesh and adjoining areas of east Rajasthan. Monsoon activity in general remained weak over areas outside central and east India.

During the first fortnight of the September, rainfall was mainly confined to east, northeast and south peninsula. With the formation of a low pressure area over northwest Bay of Bengal on 19th September and its westward movement across the central parts of the country, the monsoon activity revived. Even after the dissipation of the low pressure area on 23rd, the remnant of the system as an upper air cyclonic circulation remained quasi- stationary over Gujarat State. Under the influence of this cyclonic circulation, another low pressure area formed over Kutch & neighbourhood on 27th September and became less marked on 30th. The last low pressure area of the season formed over northwest Bay of Bengal and adjoining coastal areas of West Bengal and Odisha on 28th evening and persisted there till the last day of the season.

2.5 Very Severe Cyclonic Storm “Phailin”

A Very Severe Cyclonic Storm (VSCS) PHAILIN originated from a remnant cyclonic circulation from the South China Sea. The cyclonic circulation lay as a low pressure are over Tenasserim coast on 6th October 2013. It lay over north Andaman Sea as a well marked low pressure area on 7th October. It concentrated into a depression over the same region on 8th October near latitude 12.00N and longitude 96.00E. Moving west-northwestwards, it intensified into a deep depression on 9th morning and further into cyclonic storm (CS), „PHAILIN’ in the same day evening. Moving northwestwards, it further intensified into a severe cyclonic storm (SCS) in the morning and into a VSCS in the forenoon of 10th Oct. over east central Bay of Bengal.

 VSCS PHAILIN is the most intense cyclone that crossed India coast after Odisha Super Cyclone of 29th October 1999.  There was rapid intensification of the system from 10th Oct. morning to 11th October morning leading to an increase in wind speed from 45 knots to 115 knots.  At the time of landfall on 12th Oct, maximum sustained surface wind speed in association with the cyclone was about 115 knots (215 kmph) and estimated central pressure was 940 hPa with pressure drop of 66 hPa at the centre compared to surroundings  It caused very heavy to extremely heavy rainfall over Odisha leading to floods, and strong gale wind leading to large scale structural damage and storm surge leading to coastal inundation over Odisha.  Maximum rainfall occurred over northeast sector of the system centre at the time of landfall. Maximum 24 hr cumulative rainfall of 38 cm has been reported over Banki in Cuttack district of Odisha.

The track of VSCS “Phailin” is shown in Fig. 2.3 and the Radar image of Doppler Weather Radar at Visakhapatnam is shown in Fig. 2.4

2.6 WITHDRAWAL OF SOUTHWEST MONSOON

The weather over the western parts of Rajasthan remained mainly dry for more than a fortnight (from 27th August). A change over in the lower tropospheric circulation pattern over the region from cyclonic to anti cyclonic during 8th - 9th September resulted in the withdrawal of southwest monsoon from the region. Hence the withdrawal of southwest monsoon commenced from 9th September and the withdrawal line passed through Ganganagar, Bikaner and Barmer during 9th-18th September. The Southwest Monsoon withdrew from entire Jammu & Kashmir, Himachal Pradesh and Punjab; some parts of Haryana; some more parts of Rajasthan and some parts of Kutch on 19th and the withdrawal line passed through Kalpa, Hissar, Jodhpur and Naliya. However, an almost complete revival in the monsoon activity occurred from the 3rd week of September. With the successive formation of two low pressure areas and their westward movement across the central parts of the country caused the east-west trough to remain active contributing to above normal rainfall during this period. This development has stalled the further withdrawal of southwest monsoon.

The withdrawal was further delayed due to the formation of “Phailin” and finally the south west monsoon withdrew from the entire country on 21st October 2013.

Fig.2.5 shows the isochrones of withdrawal of monsoon 2013.

Fig. 2.5 Isochrones of withdrawal of southwest monsoon - 2013

2.7 Formation of Well marked low pressure area between 24th and 27th October 2013

A well-marked low pressure area formed in West-central Bay of Bengal on 23rd and was lying over Coastal Andhra Pradesh and adjoining areas on 24th and 25th October and weakened to a low pressure area on 26th and was lying over Telangana and neighbourhood. On 27th, the low pressure area was seen over North Coastal Andhra Pradesh and neighbourhood and became less marked in the evening of 27th.

CHAPTER 3

FLOOD FORECAST PERFORMANCE

3.1 FLOOD FORECASTING EVALUATION - PRESENT CRITERIA AND PROCEDURE

A number of techniques are being utilised for formulation of river stage and inflow forecasts by Central Water Commission. While inflow forecast is being provided for assisting project authorities in reservoir regulation, the stage forecast is done for warning the civil and engineering authorities about the predicted water level well ahead of its occurrence. An accurate forecast is one where the forecast level and corresponding actual observed level exactly synchronize or have such a small difference that it can be taken as reasonably accurate. In an ideal situation, not only the forecast and the corresponding observed value of river stage/ inflow should be the same but also the time of such occurrence should be the same as that predicted.

3.2 EVALUATION CRITERIA FOR STAGE/ INFLOW FORECASTING

As per present practice, all the level and inflow forecasts are being judged by the single criteria of accuracy i.e. the actual level attained is within ± 15cm of forecasted value for stage forecasts and the actual inflow/ volume received in the dam/ barrage is within ± 20% of the forecasted value for inflow forecast. However, the analysis of the forecasts data of individual sites has indicated that the application of uniform criteria to all sites is misleading especially for flashy rivers where rate of change in river level / inflow is sudden / abrupt and large in magnitude. Therefore, there is a need of setting different yardsticks for judging accuracy of flood forecasts for flashy and flat rivers.

The forecast of incoming flood gives the water level or inflow and “time” of occurrences. It is also observed that in many cases the levels attained were found within permissible limit of accuracy but the time of occurrence was not the same. This factor is not presently being taken into account while judging the accuracy of forecasts.

3.3 FLOOD FORECASTING ACTIVITIES

The flood forecasting activities like data collection, forecast formulation and its dissemination during 2013 covered various river basins and States. A total of 5031 forecast were issued during 2013. The performance of flood forecasting Divisionwise, Major Basinwise, Statewise and for the period 2000 to 2013 are given from Annex-IV to VII.

3.4 RIVERWISE DETAILS OF FLOOD FORECASTING ACTIVITES & ACCURACY OF FORECAST

3.4.1 Brahmaputra Basin

During the flood season 2013, analysis of the flood forecasts issued reveals that out of 1744 forecasts (24.70% of 7060 forecast) were issued for 23 sites located on the main Brahmaputra and tributaries. Out of these, 1726 forecasts (98.97%) were found within permissible limit of accuracy.

3.4.2 Barak and Meghna Basin

During the flood season 2013, 48 forecasts (0.68% of 7060) were issued for four sites. Out of these, 48 forecasts (100%) were found within permissible limit of accuracy. No forecast was issued for one site.

3.4.3 Ganga Basin

During the flood season 2013, 3190 forecasts (45.18% of 7060) were issued for 71 sites, out of total 87 sites located on the main Ganga and its tributaries. No forecast was issued for the remaining 16 sites. Out of these, 3081 forecasts (96.58%) were found within permissible limit of accuracy.

3.4.4 Eastern Rivers Basins including Mahanadi

During the flood season 2013, 221 forecasts (3.13% of 7060) were issued for eight sites out of nine sites on Eastern Rivers (excluding Mahanadi Basin) and 202 (91.40%) forecasts were found within permissible limit of accuracy. No forecasts were issued for one station. Also 85 forecasts (1.20% of 7060) were issued for two sites out of four located on the Mahanadi river basin, of which 84 forecasts (98.82%) were found within permissible limit of accuracy. Forecasts were not issued for two stations.

3.4.5 Godavari Basin

During the flood season 2013, 749 forecasts (10.61% of 7060) were issued for 13 forecasting sites out of 18 sites, out of which 626 forecasts were found with 83.58% accuracy. No forecasts were issued for the remaining five flood forecasting sites.

3.4.6 Krishna Basin

During the flood season 2013, 564 forecasts (7.99% of 7060) were issued for eight forecasting sites out of nine sites and 538 forecasts (95.39 %) were found within permissible limit of accuracy. No forecast was issued for one site in Krishna basin.

3.4.7 Southern Rivers Basin

Since the North Pennar River did not cross Warning Level, no forecast was issued for one site in Southern River System.

3.4.8 West Flowing Rivers

During the flood season 2013, for the West-flowing Rivers which comprises of the Narmada, the Tapi etc, 459 forecasts (6.50% of 7060) were issued for 11 sites, out of fifteen sites. 455 forecasts (99.13 %) were found within permissible limit of accuracy. Forecasts were not issued for four sites.

The Basinwise – Riverwise flood forecasting information in India during flood season 2013 is given in Annex-II.

3.5 STATEWISE FLOOD FORECASTING PERFORMANCE

There are 15 states, one Union Territory of the Dadra & Nagar Haveli, and National Capital Territory of Delhi so far covered under the Flood Forecast and Warning Network of the Central Water Commission. The Statewise flood forecasting information in India during the flood season 2013, is given in Annex –III. Their salient features are as under:

3.5.1 Andhra Pradesh

In the state of Andhra Pradesh, there were sixteen forecasting sites including seven inflow sites. Forecasts were issued for fourteen forecasting sites out of which there were 6 inflow and 8 level sites.

It is revealed that 921 forecasts (601 level and 320 inflow) were issued out of which 814 forecasts (510 level and 304 inflow) were within limits respectively (88.38%). No forecasts were issued for 2 stations.

4.11 AN OVERVIEW OF FORECAST EVENTS

The highlight of this year is as follows:

4.11.1 Unprecedented Flood Situation

4.11.1.1 Srinagar on river Alaknanda

 Very heavy to exceptionally very heavy rainfall recorded during the period 14th to 18th June 2013. Maximum rainfall of the order of 34 cm was recorded in the catchment areas of rivers Alaknanda resulting in rise in water levels in most of the rivers.  River Mandakini crossed it previous HFL at CWC HO Site Chandrapuri (Uttarakhand) and Rudraprayag, River Alaknanda crossed HFL at Rudraprayag and Srinagar (new HFL 537.90m and previous HFL 536.85m), River Ganga crossed previous HFL at Deoprayag during 16th- 17th June.  Since the Warning Level was very high, no flood forecast was issued for this station during the above flood spell.

4.11.1.2 Mawi on river Yamuna

 Very heavy to exceptionally very heavy rainfall occurred during the period 14th to 18th June 2013. Maximum rainfall of the order of 41 cm was recorded at Paonta in Himachal Pradesh in the catchment areas of rivers Yamuna and its tributaries. This gave rise to rapid rise in water levels in upstream and middle reaches of Yamuna.  At Hathnikund Barrage, the releases into Yamuna river have gradually increased from 45683 cusec (0600 hrs on 16-06-2013) to 806464 cusec (0600 hrs on 17-06-2013) and thereafter, the releases decreased rapidly to less than 20000 cusec(0600 hrs on 22-06-2013).  The release of 8.06 lakh cusec is the highest on record at Hathnikund Barrage. Before this a maximum of 7.06 lakh cusec and 7.44 lakh cusec was released during 1978 and 2010 respectively.  River Yamuna crossed the previous Highest Flood Level (HFL of 232.45m) at Mawi in Uttar Pradesh on 18th June 2013 attaining peak level of 232.75m

4.11.1.3 Bhagalpur on river Ganga  River Ganga flowed in Unprecedented Flood Situation (Water Level has exceeded the previous Highest Flood Level (HFL)) at Bhagalpur in Bihar during the period 29th August to 7th September 2013. The river attained new HFL of 34.50m (previous HFL 34.20m) between 3rd to 4th September.

This was in association with heavy rainfall in its catchment as well as heavy flows in Ganga downstream of its confluence with Yamuna. 4.11.2 High Flood events High Flood Situation was witnessed in 21 flood forecasting stations in the basins of Ganga, Yamuna, Ghaghra, Rapti and Kosi flowing in Uttarakhand, Uttar Pradesh and Bihar, Brahmaputra, Desang in Assam, Wardha in Maharashtra, Subarnarekha and Burhabalang in Odisha. 4.11.3 Moderate to Low flood events and inflow forecasts Moderate to low flood events were witnessed in 116 stations and inflow forecasts were issued in 24 IF Stations. 4.11.4 No Forecasts No flood forecasts were issued at 35 flood forecast stations (31 level and 4 inflow) as they did not cross warning level or flows above criteria in case of inflow forecasts.

4.11.5 Flood events in association with “Phailin”

The VSCS, PHAILIN crossed Odisha & adjoining north Andhra Pradesh coast near Gopalpur (Odisha) around 1030 hrs IST of 12th October 2013 with a sustained maximum surface wind speed of 200-210 kmph gusting to 220 kmph. Very Severe Cyclonic storm „Phailin‟ during the period 12th to 16th October 2013 gave rise to heavy to very heavy rainfall in the States of Odisha, Jharkhand, West Bengal, Bihar.

Due to this rainfall situation, High flood situation was witnessed in Subarnarekha and Burhabalang basins, Moderate to low floods were witnessed in Ganga, Damodar, Ajoy, Kangsabati, Tista, Bagmati, Punpun, Kosi, Kamlabalan basins.

A total of 162 flood forecasts were issued and Special reports on flood situations were issued on daily basis to various agencies for taking up relief and rescue operations. Details of “Phailin” related rainfall and flood situation is given in Annex-XIII

4.11.6 Flood Situation Reports for other basins

Flood situation reports for various basins such as Sutlej, Bhakra, West flowing rivers of Rajasthan, Narmada, Cauvery and Edamalayar basins were issued by collecting and compiling reservoir level and water level observations from various State Government and CWC field offices during the flood season to give the latest status on flood situation to Secretary (WR). Flood situation reports were sent to all higher authorities in association with various waves of floods in the country as well as for specific basins.

4.11.7 Flood events during February 2013 on river Yamuna

Due to very heavy rainfall in association with a Western Disturbance moving over Uttarakhand, heavy rainfall occurred in Himachal Pradesh, Uttarakhand and in the plains of Western Uttar Pradesh, Haryana and Delhi which gave rise to a low flood event in February 2013. Due to availability of telemetry data in the Central Flood Control Room this wave of flood was noticed and flood forecasts were issued by the concerned division for the flood forecast stations at Mawi and Delhi Railway Bridge.

CHAPTER 5

DIVISIONWISE USE OF TELEMETRY AND MATHEMATICAL MODEL DURING FLOOD SEASON 2013

5.1 CHAMBAL DIVISION, JAIPUR

The Telemetry system in Chambal Basin was established in the year 1999, under Dam Safety Assurance and Rehabilitation Project (DSARP), with a view to improve the quality/accuracy of the forecast and to enhance the warning time through automated Data collection and transmission system by adopting the latest technology of communication and techniques of flood forecasting formulation.

Under this Division, Telemetry Systems with various sensors like Rain Fall Sensors, Water Level Sensors, Temperature Sensors, Wind Speed and Wind direction sensors, Radiation Sensors etc have been installed at 22 sites in the upper catchment of Gandhisagar Reservoir out of 30 remote sites. The data at all the 22 sites are automatically collected from each sensor for the each hour is recorded by DCP installed at each of these sites. Most of the sites are having water level as well as rainfall sensor common.

The inflow flood forecast for Gandhi Sagar Dam is being formulated by using MIKE-11 software developed by DHI using Telemetry system data. Water level from 13 telemetry sites installed in the reservoir catchment is observed on hourly basis and is transmitted to control room on hourly basis. These Real time hourly rainfall and water level received through telemetry systems are used for formulation of the forecast. During 2013, 17 forecasts were issued for Gandhisagar Dam using Telemetry system and Mathematical Model, out of which all 17 forecasts were within the limit of accuracy i.e. ±20%.

The MIKE 11 model of Gandhisagar Dam consists of rainfall—runoff model (NAM) of various sub-basins viz. SUB-1, SUB-2C, SUB-4, SUB-5, SUB- 6, SUB-7, SUB-8 WITH CATCHMENT AREAS 2804, 108, 1761, 2065, 2373, 2672, and 1598 sq km respectively and coupled with Hydrodynamic model and Boundary conditions. Boundary conditions at two stations namely Tal on river Chambal and Mahidpur on river Shipra have been incorporated in the model. Water level and discharge data of these two sites have been incorporated in the model.

5.2 EASTERN RIVER DIVISION (ERD), BHUBANESHWAR

There are thirty three (33) Telemetry stations installed under ERD, Bhubaneswar on the Rivers Subarnarekha, Burhabalang, Baitarni, Brahmani, Rishikulya and Vamsadhara with most of the stations observing the parameters as Water Level and Rainfall except some stations observing Evaporation, Pressure, RH, Sun radiation, Wind direction, Wind Speed in

43 addition to Water Level and Rainfall. Telemetry data were used in flood forecasting calculations using MIKE 11 and NWSRFS. For the entire monsoon of 2013, forecasts for sites Anandpur (Baitarni), Gunupur and Kashinagar on Vamsadhara were calculated daily by MIKE-11 irrespective of whether the water levels crossed the warning levels or not. The results obtained were encouraging, especially when the precipitation in the basin was significant, the difference between actual and forecasted value matched very closely.

5.2.1 MIKE 11 FOR VAMSADHARA BASIN

For Vamsadhara basin, MIKE 11 is being run for the last four years. Cross sectional surveys have been done and data have been entered in the Hydrodynamic module at various levels and the results were encouraging. Every year a few modifications/upgradation are done taking into considerations for the experience gathered during the previous monsoon season with an eye to increase the effectiveness of the simulation files.

5.2.2 MIKE 11 FOR BAITARNI BASIN

MIKE 11 was also run daily during 2013 for Baitarni basin to help in issuing forecast for the site Anandpur. The site is flashy in nature and the travel time from its base station Swampatna, varies from 5-7 hours. Though there are only two cross sections available in the basin, yet the results are encouraging. Anandpur forecasts can be issued from the results of MIKE-11 with full confidence and within reasonable accuracy if more cross-sections are made available for which action is being initiated.

5.2.3 MIKE 11 FOR SUBARNAREKHA BASIN

During 2013, a humble beginning was made by incorporating Subarnarekha basin in MIKE-11. The work of calibration of the basin was completed earlier using past data and trial run was done daily using real time data during monsoon 2013. The results are encouraging and from next year it can be of great assistance to the forecast team. To increase the effectiveness of the programme, cross sectional data along the river is required to be incorporated in the Hydrodynamic model. It is proposed that cross sectional survey along the river will be carried out in the coming year and then the data will be incorporated in the programme.

5.3 MAHANADI DIVISION, CWC, Burla

Fourty one (41) stations were installed under IX/X Plan. During season 2013, all 41 stations did not report any reliable data at all from June to September while in October, most of the stations started reporting data. Mike-11 model has been developed for formulation of inflow forecast to Hirakud Dam and the same was run during monsoon with satisfactory results. The model has been developed during DSARP under IX Plan. The

44 software key received under the IX Plan has outlived its utility and a new software and software key has to be procured for this division to continue running the model in the changed operating system softwares available in the computer.

5.4 LOWER GODAVARI DIVISION, HYDERABAD (GODAVARI CIRCLE, HYDERABAD)

Under the X Plan scheme ―Establishment and Modernisation of flood forecasting including Inflow Forecasting‖, all the 63 proposed Telemetry Stations have already been installed and data from these stations were received on real –time basis. The stations transmit hourly water levels and rainfall every 15 minutes. Real – time data from telemetry is also additionally being used for flood forecasting purpose from the year 2008 onwards.

Mike-11 forecast model had been under development for the reach between Perur and Bhadrachalam. Already a model was set up for the reach in the office of CE, KGBO, Hyderabad. The model is now under trial – run. The Flood Control Application Directorate, CWC, New Delhi is actively working with KGBO to improve the model so that it can be used in real time forecast. Model calibration work has already been taken up by Morphology Directorate, CWC, New Delhi for Jaikwadi Dam. The main aim of Mike-11 usage is to modernize the methodology of flood forecasting formulation and to give it much needed look of sophistication which is lacking in the conventional method. Efforts will be made to use Mike-11 more and more in the years to come.

5.5 LOWER KRISHNA DIVISION, HYDERABAD (KRISHNA AND PENNAR BASINS/KRISHNA AND COORDINATION CIRCLE)

A total of forty one (41) Telemetry Stations, have been installed in the Krishna Basin under the X plan scheme of Establishment and Modernization of Flood Forecasting Network including Inflow Forecast during the year 2007. The data from 21 stations out of 41 stations have been received on real time basis during the monsoon period (June to September 2013) and effectively used in flood forecast formulation while rest 20 stations did not reported reliable data during the above period. Further, during October 2013, 40 stations reported data in the modelling centre. Water level data from Sadalga through Telemetry was used for formulation of Inflow Forecast to Almatti Dam. During training models were setup for inflow forecast of Srisailam and Almatti Dam. The models will be tried during monsoon season.

Odisha

In anticipation of rainfall due to cyclone, the Chandil dam started releasing water from 10th October in the order of 1000 to 1300 cumec to bring down the reservoir level from 181 m to 179 m on 13th October. Due to heavy to very heavy rainfall due to cyclone, the reservoir level again rose to 181.60 m on 16th morning which was brought down to 181 m by 17th October. Due to releases from Chandil Dam in the range of 1300 cumec and contributions from intervening catchment including Kharkai, a tributary of river Subarnarekha joining downstream of Chandil Dam, the discharge from Galudih Barrage was around 7,000 cumec which combining with the very heavy rainfall in the downstream areas created flooding in West Medhinipur district of West Bengal between 14th and 18th October 2013and a High Flood Situation at Rajghat in Balasore District of Odisha on river Subarnarekha. The river flowed in High Flood Situation from 16 hrs of 14th October 2011 to 12 hours of 15th October 2013. The peak level attained was 12.42 m from 0100 hrs to 0500 hrs on 15th October 2013.
